Which UPS to buy for my Server?

[LazySloth]

Well, I got this Secondhand server of the config in the image. I want to buy a UPS for it but have any clue about them. It has to back up the server monitor and a printer for at least 4hr, I understand that UPS are not meant for the sustained load so what other way is there to get this amount of backup.

Power supply specs: Supermicro 560W/600W 1U Multi-Output Power Supply (PWS-563-1H).

Do you know the actual power draw of your server?
Most servers have a huge power supply to deal with them running at 100%, but actually they run at a Wattage much lower than that.

 

So for example if your server is mostly idle, then you can expect maybe a 100Watt draw.
The Normal usage in Watts will determine the size of your USP.

That being said Eaton do a nice calculator to give you an idea of what you should be looking at;

It is however designed around the enterprise market but you can figure out what you should be looking at.

A 4hour USP for even 200Watts is not going to be cheap though.

Get multiple  UPS devices if one caan't cut it.  One for each component.
